​Efficient energy use, sometimes simply called energy efficiency, is using less energy to provide the same level of energy service.
For example, insulating a home allows buildings to use less heating and cooling energy to achieve and maintain a comfortable temperature. Cheap solarsells could be made more energy efficient through a simple process, it has been reported.
The New Scientist has highlighted a technique developed by chemists at Indiana University in Bloomington.
To reduce waste energy is turn off the light if we don't need.
